Caching Plugins and How They Speed Up Your Site
Every time someone visits a WordPress page, the server normally rebuilds it from scratch — running code and querying the database. Caching saves a ready-made copy so repeat visits are served almost instantly.
It is one of the most effective ways to make a WordPress site feel fast.
Types of Caching
- Page caching: stores the finished HTML of a page.
- Browser caching: keeps assets on the visitor's device.
- Object caching: remembers repeated database results.
- CDN caching: serves files from servers near the visitor.
The Catch: Stale Content
The downside of caching is that changes may not appear immediately, because visitors see the saved copy. This is why an edit sometimes seems to 'not save' until the cache is cleared.
How We Manage It
- Choose a caching plugin suited to your hosting.
- Exclude pages that must always be live, such as carts.
- Clear the cache automatically when content changes.
Frequently Asked Questions
I edited a page but cannot see the change. Why?
It is almost always caching. Clearing the site cache, or waiting a few minutes, will show your update.
